The user IF 13 may be a set of a display, a keyboard, a mouse, a trackball, and the like. The user IF 13 is an example of a display device.

The communication IF 14 includes various hardware for communicating with an external device. The communication IF 14 includes, for example, an NFC (abbreviation of “Near Field Communication”) interface (hereinafter referred to as “NFC-IF”) 141 and a wireless LAN interface (hereinafter referred to as “wireless LAN-IF”) 142. include. NFC-IF141 is an interface that enables NFC-type wireless communication based on the international standard of ISO / IEC21481 or ISO / IEC18092. The wireless LAN-IF142 is an interface that enables Wi-Fi (registered trademark) type wireless communication based on the IEEE 802.11 standard and a standard equivalent thereto. The communication IF 14 may further include a configuration corresponding to another communication standard, and may include, for example, Bluetooth (registered trademark) or hardware for performing wired communication.

The position information acquisition unit 15 is configured to acquire information indicating a geographical current position by using, for example, a global positioning system (hereinafter referred to as “GPS”), and is, for example, a GPS receiver. And a positioning function using GPS. The geographical current position is, for example, information on a set of latitude and longitude indicating the current position on the earth.

As shown in FIG. 1, the memory 12 of the information processing terminal 1 of the present embodiment stores the device setting application 121 and the connection information database (hereinafter referred to as “connection information DB”) 122. The device setting application 121 is a program that performs processing for connecting an electronic device to a wireless network. The device setting application 121 is an example of a program. The connection information DB 122 is a database that stores connection information used for setup for connecting to an access point of a wireless network.

An access point is a communication device for connecting various devices to a wireless network such as the Internet or LAN by Wi-Fi wireless communication. Unique connection information is set for each access point. The device that uses the access point needs to complete the setup, which is the procedure for connecting to the access point, using the connection information of the access point. The Wi-Fi wireless communication using an access point is an example of the first communication system.

The connection information is, for example, a set of identification information for identifying an access point (hereinafter referred to as "SSID" (abbreviation of Service Set IDentifier)) and a password set in advance corresponding to the SSID. The apparatus performing the setup sends the correspondingly set password to the access point specified by the SSID, and completes the setup by acquiring the IP address issued from the access point. The connection information may be one combination information (Wi-Fi Easy Connect connection information) in which the SSID and the password are combined. Passwords and combination information are examples of authentication information.

As shown in FIG. 1, the information processing terminal 1 of the present embodiment has been set up for a plurality of access points including the access point 3 and the access point 4. The connection information DB 122 of the information processing terminal 1 can store a plurality of connection information including the connection information of the access point 3 and the connection information of the access point 4. The information processing terminal 1 acquires the connection information of the access point and stores it in the connection information DB 122 by, for example, executing the device setting application 121.

Further, if the information processing terminal 1 has a set-up access point within a predetermined range capable of wireless communication in the Wi-Fi system, the information processing terminal 1 is automatically connected to the access point. For example, as shown in FIG. 1, when the current position of the information processing terminal 1 is outside the predetermined range from the access point 3 and within the predetermined range from the access point 4, the communication IF 14 of the information processing terminal 1 is the access point. Connected to 4.

Further, the information processing terminal 1 of the present embodiment executes the device setting application 121 to pass the connection information to the electronic device and perform the device setting process for completing the setup of the electronic device. The electronic device 2 shown in FIG. 1 is a device that is the target of the device setting process by the information processing terminal 1, and is not connected to the wireless network before the device setting process is executed. The electronic device 2 is a device having at least a wireless communication function, and is, for example, a multifunction device, a printer, a scanner, a fax machine, a sewing machine, and a camera.

As shown in FIG. 1, the electronic device 2 includes a controller 20 including a CPU 21 and a memory 22. Further, the electronic device 2 includes a user IF 23 and a communication IF 24, which are electrically connected to the controller 20. The user IF 23 is, for example, a touch panel, and includes hardware for displaying a screen for notifying the user of information and hardware for accepting an operation by the user. The communication IF24 includes, for example, NFC-IF241 and wireless LAN-IF242, and may further include a configuration corresponding to other communication standards, such as Bluetooth and hardware for performing wired communication. In addition to the configuration shown in the figure, the electronic device 2 has a configuration for realizing the functions of each device. For example, a printer has a configuration for printing, and a scanner has a configuration for reading an image.

While the power is turned on, the electronic device 2 is in a state of detecting an information processing terminal capable of executing NFC-type wireless communication by a signal periodically emitted from the NFC-IF241. For example, when the information processing terminal 1 with the NFC function enabled comes close to the NFC-IF241 within a predetermined distance range, the electronic device 2 detects the close information processing terminal 1 and and the information processing terminal 1 Wireless communication by the NFC method with the electronic device 2 is automatically enabled. The NFC method is different from the Wi-Fi method in that the communication range is narrower and the communication speed is slower than the Wi-Fi method. Wireless communication by the NFC method is an example of the second communication method. Since the information processing terminal 1 is a portable device, the user can bring the NFC-IF141 of the information processing terminal 1 close to the NFC-IF241 of the electronic device 2.

The electronic device 2 is further provided with a wireless LAN access point function, and can support Wi-Fi Direct (hereinafter referred to as "WFD") wireless communication. That is, the electronic device 2 stores the connection information of the WFD method, becomes a group owner device that manages the network, and has a function of constructing a network with the client device. The WFD method is different from the NFC method in that the communication range is wider and the communication speed is faster than the NFC method.

Specifically, the electronic device 2 transmits, for example, the connection information of the WFD system of its own device by the NFC system when wireless communication by the NFC system becomes possible. When the information processing terminal 1 receives the WFD connection information in the NFC system, the information processing terminal 1 becomes a client device by transmitting the received WFD connection information via the wireless LAN-IF142, and becomes a client device with the electronic device 2. Communication by the WFD method becomes possible.

The setup application 221 is stored in the memory 22 of the electronic device 2. The setup application 221 is a program that cooperates with the device setting application 121 of the information processing terminal 1 to perform setup for connecting to the access point using the connection information transmitted from the information processing terminal 1.

Subsequently, the outline of the device setting procedure for completing the setup in the electronic device 2 by using the device setting application 121 of the information processing terminal 1 of the present embodiment will be described with reference to the sequence diagram of FIG. The procedure shown in FIG. 2 is a procedure for connecting the electronic device 2 to the wireless network using the access point 4. In FIG. 2, the processing of the information processing terminal 1 is executed by the CPU 11, and the processing of the electronic device 2 is executed by the CPU 21.

When the device setting application 121 is activated by the user (T01), the information processing terminal 1 causes the user IF 13 to display an instruction receiving screen including a button for receiving the user's instruction (T02). The device setting application 121 of the present embodiment displays, for example, the connection information input button 51 and the device setting button 52, as shown in FIG. 3A. The connection information input button 51 is a button that receives an instruction to add new connection information to the connection information DB 122 or edit the stored connection information. The device setting button 52 is a button that receives an instruction to select one of the information stored in the connection information DB 122 and set it in the target electronic device.

Then, the information processing terminal 1 waits until it receives an input to any of the buttons (T03). When the received button is the connection information input button 51 ([information input]), the information processing terminal 1 causes the user IF 13 to display the connection information edit screen (T04). For example, as shown in FIG. 3B, the information processing terminal 1 includes an additional button 53 for receiving an additional instruction for connection information, a plurality of edit buttons 54 for receiving an edit instruction for each stored connection information, and the like. Display the screen including.

Then, when the operation to the add button 53 is accepted, the information processing terminal 1 displays, for example, an input field for the SSID and the password and the registration button 55, as shown in FIG. 3C. , Accept input. Further, when the operation to the edit button 54 is accepted, the information processing terminal 1 displays, for example, the registered SSID and password and updates the column for accepting editing, as shown in FIG. 3D. Button 56 and are displayed.

When the information processing terminal 1 receives an input instruction of the connection information being displayed by operating the registration button 55 or the update button 56 (T05), the information processing terminal 1 uses the position information acquisition unit 15 to determine the current position at that time. The information to be shown is acquired (T06). Further, the information processing terminal 1 associates the connection information for which the input instruction is received at T05 with the position information acquired at T06 and stores it in the connection information DB 122 of the memory 12 (T07).

An example of the connection information DB 122 is shown in FIG. The connection information DB 122 of this example stores the information of the set of the SSID and the password as the connection information and the information of the set of the latitude and the longitude as the position information in association with each other. The connection information is the information received at T05, and the location information is the information acquired at T06. Since the user who inputs the connection information inputs the connection information while confirming the connection information described in the access point or its manual, there is a high possibility that the user is near the access point. That is, the position information stored in the connection information DB 122 is likely to be information indicating a position close to the geographical position of the access point indicated by the corresponding connection information.

On the other hand, when the input to the device setting button 52 is accepted on the screen shown in FIG. 3A ([Settings]), the information processing terminal 1 acquires the position information of its own device (T08). Based on the acquired information, the connection information satisfying a predetermined condition is selected from the connection information DB 122 stored in the memory 12 as the connection information to be set up by the electronic device 2 (T09). For example, as shown in FIG. 5 (E), the information processing terminal 1 displays a list of each connection information stored in the connection information DB 122 and accepts the user's selection (T10). The details of the processing in T08 and T09 will be described later.

When the connection information is selected, the information processing terminal 1 enables the NFC function of its own device, and holds the information processing terminal 1 over the electronic device 2 to be set, for example, as shown in FIG. 5 (F). The instruction message is displayed on the user IF13 (T11). When the information processing terminal 1 is held over the electronic device 2 by the user (T12), the information processing terminal 1 receives the WFD connection information from the electronic device 2 via the NFC-IF141 (T13), and makes a WFD connection. Request to electronic device 2. As a result, WFD wireless communication becomes possible between the information processing terminal 1 and the electronic device 2 (T14).

The information processing terminal 1 transmits an instruction to start the setup application 221 and start the setup process to the electronic device 2 by the WFD method (T15). The electronic device 2 activates the setup application 221 (T16), and transmits information indicating that the activation is completed to the information processing terminal 1 (T17). After receiving the activation completion information, the information processing terminal 1 transmits the connection information selected in T09 to the electronic device 2 (T18). The electronic device 2 receives connection information from the information processing terminal 1 at T18.

The electronic device 2 searches for the corresponding access point using the SSID included in the received connection information (T19). Then, when the corresponding access point is searched ([Yes]), the electronic device 2 transmits the password included in the connection information to the access point (T21). If the selected connection information is the connection information of the access point 4, the electronic device 2 transmits the connection information to the access point 4.

When the access point 4 receives the appropriate connection information, it assigns an IP address to the electronic device 2 that has transmitted the connection information, and transmits the assigned IP address to the electronic device 2 (T22). Since the electronic device 2 has completed the setup to the wireless network using the access point 4 by receiving the IP address, it transmits a completion notification to the information processing terminal 1 (T23). As a result, as shown in FIG. 6, the connection information 222 of the access point 4 is stored in the memory 22 of the electronic device 2, and the electronic device 2 and the access point 4 can be connected to each other.

On the other hand, if the access point corresponding to the connection information received in T18 is not searched ([None]), the electronic device 2 cannot complete the setup, and therefore sends an error notification to the information processing terminal 1. (T24). Alternatively, even if the connection information is transmitted to the access point 4, but the error information is received from the access point 4 instead of the IP address, the electronic device 2 transmits the error notification to the information processing terminal 1.

The information processing terminal 1 disconnects the WFD method connection after T23 or T24 (T25). When the information processing terminal 1 receives the completion notification, the information processing terminal 1 may be connected to the electronic device 2 by the Wi-Fi method. Further, when the information processing terminal 1 receives the error notification, the selection screen may be displayed again to accept the selection of another connection information.

Next, the procedure of the device setting process executed by the information processing terminal 1 in order to complete the setup of the electronic device 2 will be described with reference to the flowchart of FIG. 7. The device setting process is executed by the CPU 11 of the information processing terminal 1 when the device setting application 121 is started by the information processing terminal 1. The device setting application 121 may be, for example, a part of an application for causing the multifunction device to perform printing or scanning. That is, the device setting process may be executed when the device setting instruction is received during the execution of another application.

In the device setting process, the CPU 11 first causes the user IF 13 to display the instruction reception screen (T02, S101). As shown in FIG. 3A, the instruction receiving screen includes a connection information input button 51 and a device setting button 52, and is a screen for receiving any instruction. Then, the CPU 11 determines whether or not the instruction for inputting the connection information has been received by operating the connection information input button 51 (T03, S102). When it is determined that the instruction for inputting the connection information is not accepted (S102: NO), the CPU 11 determines whether or not the instruction for device setting is accepted by operating the device setting button 52 (S103). If it is determined that the device setting instruction is not accepted (S103: NO), the CPU 11 waits until any instruction is accepted.

When it is determined that the instruction for inputting the connection information has been accepted ([Information input], S102: YES), the CPU 11 has registered the connection from the connection information DB 122 on the edit screen as shown in (B) of FIG. The information is read out and displayed in a list on the user IF13 (T04, S104), and an operation to the add button 53 or the edit button 54 is accepted. Then, the CPU 11 determines whether or not an additional instruction has been received by operating the add button 53 (S105). When it is determined that the additional instruction is not accepted (S105: NO), the CPU 11 determines whether or not the edit instruction has been accepted by operating the edit button 54 (S106). If it is determined that the editing instruction is not accepted (S106: NO), the CPU 11 waits until any of the instructions is accepted.

When it is determined that the additional instruction has been accepted (S105: YES), the CPU 11 causes the user IF 13 to display an input field for accepting the input of connection information as shown in FIG. 3 (C), and accepts the input by the user. (S107). Further, the CPU 11 determines whether or not the registration instruction by operating the registration button 55 has been accepted (S108), and if it determines that the registration instruction has not been accepted (S108: NO), waits until it is accepted. The operation of the registration button 55 may not be accepted if it has not been entered in the input field. In addition, there may be a button that accepts an instruction to cancel the registration and return to the previous screen.

When it is determined that the instruction to edit one of the registered connection information has been accepted (S106: YES), the CPU 11 displays the specified connection information on the user IF 13 as shown in FIG. 3D. And accept editing by the user (S109). In addition to editing, you may also accept instructions to delete the registration. Further, the CPU 11 determines whether or not the update instruction by operating the update button 56 has been accepted (S110), and if it determines that the update instruction has not been accepted (S110: NO), waits until it is accepted. In addition, there may be a button that accepts an instruction to cancel editing and return to the previous screen.

When it is determined that the registration instruction has been accepted (S108: YES), or when it is determined that the update instruction has been accepted (S110: YES), the CPU 11 is displaying when the registration or update instruction is accepted. The information is acquired as connection information (T05, S111). S111 is an example of the acquisition process.

Then, the CPU 11 acquires the information of the current position by using the position information acquisition unit 15 (T06, S112). The position information acquired in S112 is an example of the first position information. The CPU 11 acquires, for example, latitude and longitude information by the GPS function as information on the current position. Further, the CPU 11 associates the position information acquired in S112 with the connection information acquired in S111 and stores them in the connection information DB 122 (T07, S113). S113 is an example of storage processing. If it is an instruction to register new information, the CPU 11 newly adds connection information to the connection information DB 122 and stores it together with the location information, and if it is an instruction to update the registered information, updates the information in the connection information DB 122. ..

When the device setting application 121 is upgraded, the information processing terminal 1 takes over and uses the connection information DB 122 stored in the device setting application 121 of the old version. Further, when the information processing terminal 1 acquires the connection information of the access point by a program other than the device setting application 121, the connection information may also be stored in the connection information DB 122. Since the information processing terminal 1 can also use the connection information input by the old version program or another program, the convenience of the device setting application 121 is enhanced. Further, for example, when the connection information to which the position information is not added such as the connection information input by another program is stored in the connection information DB 122, the information processing terminal 1 receives the input instruction of only the position information. Is also good.

Then, the CPU 11 determines whether or not the instruction to end the application has been accepted (S114). If it is determined that the reception is not accepted (S114: NO), the CPU 11 returns to S101 and further accepts the connection information input instruction or the device setting instruction.

On the other hand, when it is determined that the device setting instruction has been accepted on the instruction receiving screen shown in FIG. 3A ([setting], S103: YES), the CPU 11 executes the selection setting process (S115). The selection setting process is a process of selecting one of the registered connection information and transmitting it to the electronic device 2 to be set to complete the setup of the electronic device 2. The procedure of the selection setting process will be described with reference to the flowchart of FIG.

In the selection setting process, the CPU 11 first executes the access point determination process (S201). The access point determination process is a process of determining the access point of the connection information to be passed to the electronic device 2 among the connection information registered in the connection information DB 122. The procedure of the access point determination process will be described with reference to the flowchart of FIG. In FIG. 9, the access point is abbreviated as "AP".

In the access point determination process, the CPU 11 causes the user IF 13 to display a message prompting the user to approach the electronic device 2 to be set to complete the setup (S301). The CPU 11 notifies, for example, that it is necessary to perform NFC-type communication with the electronic device 2, and prompts the user to move to a position where the electronic device 2 can reach the NFC-IF241. Further, the CPU 11 may accept an input indicating that the movement is completed when the movement is completed.

The CPU 11 determines whether or not there is an access point to which the information processing terminal 1 itself is connected while the information processing terminal 1 is near the electronic device 2 to be set (T08, S302). As described above, the information processing terminal 1 is automatically connected if wireless communication with the access point for which the setup has been completed is possible. The CPU 11 can acquire the SSID information of the currently connected access point from the operating system.

When it is determined that there is a connected access point (S302: YES), the CPU 11 selects the connection information including the password corresponding to the SSID of the connected access point as the connection information to be set in the electronic device 2 (T09). , The selected connection information is read from the connection information DB 122 (S303). S303 is an example of the selection process. As described above, the connection information DB 122 also stores the connection information input by the old version program or another program, and the CPU 11 selects the connection information from these connection information.

If there is a connected access point, it is highly possible that the information processing terminal 1 is within a predetermined distance range from the access point, and the electronic device 2 is also within a predetermined distance range from the access point. The predetermined range is, for example, not more than the maximum distance at which Wi-Fi wireless communication is possible, and may be a predetermined fixed value or a variable value based on user input. The information indicating whether or not the information processing terminal 1 itself is connected is an example of the information acquired at the current position, and the access point to which the information processing terminal 1 itself is connected is an access point that satisfies a predetermined condition. This is an example. The connection information read in S303 is an example of specific connection information.

On the other hand, when it is determined that there is no connected access point (S302: NO), the CPU 11 uses the position information acquisition unit 15 to acquire information on latitude and longitude as information on the current position (T08, S304). S304 is the same process as S112 of the device setting process. The position information acquired in S304 is an example of the information acquired at the current position, and is an example of the second position information.

Then, the CPU 11 determines that the distance from the current position is within a predetermined range from the acquired position information and the position information associated with the registered connection information stored in the connection information DB 122 of the memory 12. The connection information is extracted from the connection information DB 122. As described above, the connection information DB 122 also stores the connection information input by the old version program or another program, and the CPU 11 extracts the connection information from the connection information. The CPU 11 determines whether or not there is an extracted access point, that is, whether or not there is an access point within a predetermined range from the current position (S305).

Since the connection information is associated with information indicating the position of the information processing terminal 1 at the time of registration, the CPU 11 when the connection information is registered based on the position information of the current position acquired in S304. It is possible to determine whether or not the distance between the position and the current position is within a predetermined range. Since the connection information of the access point near the information processing terminal 1 can be acquired based on the position information, the possibility that the electronic device 2 that has received the connection information can connect to the access point is increased. An access point in which the distance between the registered position and the current position is within a predetermined range is an example of an access point satisfying a predetermined condition.

When it is determined that there is an access point at a position within the predetermined range (S305: YES), the CPU 11 determines whether or not there is only one access point within the predetermined range (S306). When it is determined that not only one but a plurality of access points are within the predetermined range (S306: NO), the CPU 11 determines that the access point within the predetermined range has the closest distance to the current position. The connection information is emphasized and displayed on the user IF13 (S307). Further, the CPU 11 preferentially displays the remaining extracted access points in the user IF 13 as the distance between the position of the connection information and the current position is closer (S308). Further, the CPU 11 accepts a user's selection operation for one of the connection information displayed in the list (S309).

For example, as shown in FIG. 5 (E), the CPU 11 emphasizes the connection information 57 of the nearest access point so as to distinguish it from the other connection information 58, and displays the other connection information 58 at a short distance. Display them side by side in order from the top. Examples of highlighting include, for example, displaying at the beginning or top, displaying in a different font (eg, bold, italic, large size, color inversion), underlining, enclosing, shading, etc. Is displayed. In the list display, only the SSID may be displayed and the password may not be displayed.

By preferentially displaying the position information close to the current position of the information processing terminal 1 from the associated connection information, if the electronic device 2 is near the information processing terminal 1, the position information close to the electronic device 2 is associated. The connection information is more likely to be selected, and as a result, the electronic device 2 is more likely to be able to connect to the access point. It is sufficient to display the ones with the closest distance preferentially. Instead of displaying them in a list, only the connection information of the closest access point is displayed first, and other connection information is also displayed when the user's instruction input is accepted. You may do so.

After S303 or S309, or when it is determined that only one access point has been extracted (S306: YES), the CPU 11 selects the connection information as the information of the access point to be set up in the electronic device 2 (S306: YES). T09, S310). That is, the CPU 11 sets up the connection information read in S303, the connection information extracted in S305, or the connection information selected in S309 as specific connection information to be set up in the electronic device 2. select. S310 is an example of the selection process.

On the other hand, when it is determined that there is no access point within a predetermined range from the current position (S305: NO), the CPU 11 causes the user IF 13 to display a message indicating that there is no access point nearby (S311). S311 is an example of notification processing. By notifying that the access point is not nearby, the user can know the possibility that the setup will fail, and the possibility that the user will be confused even if the setup fails can be reduced. After S310 or S311 the access point determination process is terminated and the process returns to the selection setting process.

Returning to the description of the selection setting process of FIG. After the access point determination process of S201 of the selection setting process, the CPU 11 determines whether or not the connection information has been selected in the access point determination process (S202). When the message is displayed in S311 of the access point determination process, the access point has not been determined and the connection information has not been selected. If it is determined that the connection information is not selected (S202: NO), the CPU 11 ends the selection setting process and returns to the device setting process.

On the other hand, when it is determined that the connection information has been selected (S202: YES), the CPU 11 causes the electronic device 2 to complete the setup using the selected connection information. Therefore, as described above, the CPU 11 starts the WFD method communication with the electronic device 2 via the NFC method, and causes the electronic device 2 to start the setup application 221 (T11 to T17, S205). The process of connecting to the electronic device 2 by the NFC method in S205 is an example of the connection process.

Further, the CPU 11 transmits the connection information determined in the access point determination process to the electronic device 2 by the WFD method as a transmission target (S207). S207 is an example of transmission processing. In S207, the CPU 11 transmits a command instructing the setup to the electronic device 2 together with the connection information.

As a result, as described above, the electronic device 2 searches for the access point corresponding to the received connection information, and transmits the connection information to the access point, for example, the access point 4 (T19 to T21). If the connection information is appropriate, the electronic device 2 receives the IP address information from the access point 4 and transmits a completion notification to the information processing terminal 1 (T22 to T23). On the other hand, when the IP address information cannot be received from the access point 4, the electronic device 2 transmits an error notification to the information processing terminal 1 (T24).

The CPU 11 determines whether or not the completion notification has been received from the electronic device 2 (S208). When it is determined that the completion notification has not been received (S208: NO), the CPU 11 determines whether or not the error notification has been received (S209). If it is determined that the error notification has not been received (S209: NO), the CPU 11 waits until the completion notification or the error notification is received.

When it is determined that the error notification has been received (T24, S209: YES), the CPU 11 determines whether or not the content of the error is a password mismatch (S210). When it is determined that the passwords do not match (S210: NO), the CPU 11 causes the user IF 13 to display a message indicating that an error has occurred (S211).

When it is determined that the content of the error is a password mismatch (S210: YES), the CPU 11 causes the user IF 13 to display the password input screen (S212), and accepts the user's input. The password input screen is, for example, a screen as shown in FIG. 3D, and accepts an update instruction. Then, the CPU 11 determines whether or not the update instruction by the user has been accepted (S213).

When it is determined that the update instruction has been accepted (S213: YES), the CPU 11 retransmits the updated connection information to the electronic device 2 (S214). S214 is an example of the retransmission process. Then, the CPU 11 determines whether or not the completion notification has been received from the electronic device 2 (S215). When it is determined that the completion notification has been received (S215: YES), the CPU 11 changes the connection information DB 122 by storing the updated connection information in the connection information DB 122 (S216). S216 is an example of the change process.

If the password of the previously stored connection information is incorrect, or the password set in the access point has been changed, the electronic device 2 cannot complete the setup. In this embodiment, in response to receiving the error notification, the input of a new password can be accepted and the appropriate connection information can be acquired, so that the possibility of completing the setup is increased. Furthermore, if the setup is successful with the newly entered password, the password is stored in the connection information DB 122, so that the setup on the other electronic device is successful when the connection information is transmitted to the other electronic device. The possibility of doing it increases.

If it is determined that the error notification has been received again without receiving the completion notification (S215: NO), the CPU 11 displays an error (S217). The CPU 11 may accept the input again.

When it is determined that the completion notification has been received from the initial connection information (T23, S208: YES), when it is determined that the instruction not to update has been accepted (S213: NO), or after S211, S216, S217, the CPU 11 , WFD communication with the electronic device 2 is disconnected (T25, S218), the selection setting process is terminated, and the process returns to the device setting process.

Returning to the description of the device setting process of FIG. 7. In the device setting process, the CPU 11 determines whether or not the end instruction has been accepted after the selection setting process of S115 is completed (S114). If it is determined that the reception is not accepted (S114: NO), the CPU 11 returns to S101 and further accepts the connection information input instruction or the device setting instruction. When it is determined that the end instruction has been accepted (S114: YES), the CPU 11 ends the device setting process and ends the device setting application 121.

As described in detail above, according to the information processing terminal 1 of the present embodiment, the setup for connecting to the access point of the wireless network by the Wi-Fi method is performed by the NFC method having a narrower communication range than the Wi-Fi method. By connecting to the electronic device 2 to be connected, it is guaranteed that the electronic device 2 is near the information processing terminal 1. Further, the information processing terminal 1 selects connection information of an access point satisfying a predetermined condition from the connection information DB 122 stored in advance based on the information of the current position of the information processing terminal 1, and connects the connection information. Information is transmitted to the electronic device 2. As a result, the connection information of the access point near the electronic device 2 is transmitted. As a result, the possibility that the electronic device 2 is within the communication range of the access point is increased, and the possibility that the setup fails can be reduced.

It should be noted that the embodiments are merely examples, and do not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist thereof. For example, a plurality of electronic devices to be set may be set. That is, if there are a plurality of electronic devices arranged in the vicinity, the information processing terminal 1 may pass the same connection information to those electronic devices.

Further, for example, the method of inputting connection information is not limited to the method of acquiring both the SSID and the password by inputting the user. For example, the information processing terminal 1 may acquire the SSID of the access point set up by its own device from the operating system, display it, and accept the input of only the password. Alternatively, if the information processing terminal 1 is provided with a camera, the information processing terminal 1 may read a QR code (registered trademark) for storing the SSID and password of the access point with the camera and acquire connection information from the read image.

Further, for example, in the embodiment, if there is a connected access point in the access point determination process, the access point is determined, but it is not necessary to determine the presence or absence of the connected access point. That is, the access point determination processes S302 and S303 may be omitted. Further, for example, in the access point determination process, if there is a connected access point, the access point is determined without accepting the user's selection, but the user's selection may be accepted. For example, the connection information of the connected access point may be highlighted to accept the user's selection.

Further, for example, when there are a plurality of access points at positions within a predetermined range, the CPU 11 may highlight frequently used access points. When the information processing terminal 1 is connected to an access point by various applications executed by the information processing terminal 1, for example, the information is stored in the connection information DB 122, and the number of times of connection is larger than a predetermined number of times. May be judged as an access point that is frequently used.

Further, for example, in the embodiment, in the selection setting process, the CPU 11 starts the NFC communication with the electronic device 2 after the connection information is determined, but the reverse order may be used. That is, when the information processing terminal 1 receives the device setting instruction, it urges the user to perform NFC communication with the target electronic device 2, starts WFD communication, and then transmits the connection information. You may accept your choice. Alternatively, the information processing terminal 1 may temporarily disconnect the connection without starting the WFD communication after confirming the NFC communication, accept the selection of the connection information, and then start the communication again. Alternatively, the information processing terminal 1 may transmit the selected connection information by NFC communication.

Further, for example, in the embodiment, the information processing terminal 1 is supposed to execute NFC communication with the electronic device 2, but it is also possible to communicate with the electronic device 2 by using other short-range wireless communication such as Bluetooth. good.

Further, for example, in the embodiment, it is assumed that the electronic device 2 is a device for which the setup for connecting to the access point 4 has not been completed, but the device may be a device for which the setup has been completed. In that case, the electronic device 2 may be set up again based on the connection information received from the information processing terminal 1. For example, if the electronic device 2 receives the connection information of the access point 4 while the electronic device 2 has completed the setup for connecting to the access point different from the access point 4, the electronic device 2 sets up the connection with the access point 4. Complete. In this case, the electronic device 2 may delete the connection information of the other access point and store only the connection information of the access point 4.

Further, for example, in the embodiment, the position information acquisition unit 15 having the GPS function is illustrated, but the position information acquisition unit 15 may be configured to include a beacon receiver. For example, when it is used in a building where a plurality of beacon transmitters are arranged, information indicating the current position may be acquired based on the beacon information received by the position information acquisition unit 15. Further, the position information acquisition unit 15 may accept the input of the user as the position information. For example, it may accept input of information indicating the number of floors of a building or a predetermined section in the floor and acquire it as information indicating the current position.

Further, for example, the position information acquisition unit 15 may acquire the SSID of the access point to which the information processing terminal 1 is connected as the position information. For example, as the position information to be stored in the connection information DB 122, the SSID of the access point to which the information processing terminal 1 is connected when the user inputs the connection information is stored. Then, in the access point determination process, the connection information in which the SSID matching the SSID of the access point to which the information processing terminal 1 is currently connected is associated as the position information may be read from the connection information DB 122. Since the communication range of wireless communication via an access point is limited, the position of the information processing terminal 1 can be estimated from the information of the access point to which the information processing terminal 1 is connected. Therefore, the SSID of the access point can be used as location information.

Further, in the sequence diagram or the flowchart disclosed in the embodiment, the plurality of processes in the arbitrary plurality of steps can be arbitrarily changed in the execution order or executed in parallel as long as the processing contents do not conflict with each other. ..

Further, the process disclosed in the embodiment may be executed by a single CPU, a plurality of CPUs, hardware such as an ASIC, or a combination thereof. In addition, the process disclosed in the embodiment can be realized in various aspects such as a recording medium or a method in which a program for executing the process is recorded.
